I have the same dilemma and I’m not all tactical and do all the tactical training but I did have some thoughts. I have a Gen 5 17 I carry if going in large crowded areas but more often I carry my 43X. Is it better to have one pistol for EDC and be very proficient with it or multiples? I want to get into shooting with a RDS and just worried about two different sight pictures between the 17 with a RDS and 43X with irons.
